DIA of racing beat tips
 

Im doing a custom setup down the road and just getting my homework on it done now.
What is the DIA of the racing beat exhaust tips? I would like the the DIA of the OUTLET of the muffler and the end tips. I know the system is 3" but does not mean the exit of the muffler is also 3". The reason for the tips is because i dont want huge ricey ones and the RB tips look to be a good size.
